Overview
Triglycidyl isocyanurate (CAS 2451-62-9 ), commercially known as TGIC, is a trifunctional epoxy compound used as a crosslinker and curing agent in thermosetting polymer systems.
It reacts with carboxyl-functional resins to build durable, chemically resistant networks, making it a standard component in high-performance coating formulations for industrial use.
TGIC is the primary crosslinker in polyester-based powder coatings, where it delivers superior outdoor durability, UV resistance, and mechanical strength in architectural finishing applications.
In the electronics industry, it contributes to epoxy encapsulants and printed circuit board laminates that require tight dimensional stability under thermal cycling and stress.
Aerospace and defense manufacturers use TGIC-cured systems in structural adhesives and composite matrices where resistance to elevated temperatures and aggressive environments is critical.
Flexible packaging printers also incorporate it into ink and coating formulations that demand strong substrate adhesion and chemical resistance across various commercial printing platforms.
TGIC is supplied as a white to off-white crystalline powder. Standard commercial grades are available at purities of 98% and above, serving the coatings and composites sectors.
Packaging typically ranges from kilogram-scale bags to bulk quantities for high-volume powder coating producers, ensuring reliable supply chains for global manufacturing operations.
